目的　探讨肺癌患者的骨髓像变化与生存期的关系。方法　抽取初诊肺癌患者的骨髓涂片经瑞氏染色后用光学显微镜进行常规细胞形态学检查 ,并记录相应的生存期。结果　 3例肺癌骨转移者 1例周内死亡 (小细胞肺癌 ) ;2例 (小细胞肺癌、腺癌各 1例 )在 3月内死亡 ;余生存分别为 5～ 2 8个月。结论　肺癌患者一旦伴骨髓转移 ,生存期比非转移者明显缩短。 Objective To investigate the relationship between bone marrow changes and survival in patients with lung cancer. Methods The bone marrow smears of newly diagnosed lung cancer patients were routinely stained with Wright’s stain and examined by light microscopy. The corresponding survival time was recorded. Results Three cases of lung cancer with bone metastasis died within one week (small cell lung cancer). Two cases (one case of small cell lung cancer and one case of adenocarcinoma) died within three months. The remaining survivals were from 5 to 28 months. Conclusion Lung cancer patients with bone marrow metastasis, survival was significantly shorter than non-metastasis.
